The police, however, said that it was a case of suicide since a purported note was also found in which he said no one was responsible for his death.
Mr Jha's family was initially not able to identify his body yesterday. But after police showed a wallet and clothes, they identified the body.
RN Mishra, Mr Jha's brother-in-law, said the body was mutilated beyond recognition and that is why they could not identify it..
"Three-four months ago, he had said that he won't live for long. He was scared for his life," Mr Mishra told news agency PTI, alleging foul play in Mr Jha's death.
Mr Mishra said that Mr Jha was scared and was not even going to work and had been on leave.
"He had even stopped visiting our house late in the night. If we had to meet him, we would have to visit his home," Mr Mishra said. Mr Jha had even started leaving his cellphone at home so that his location could not be tracked, he said.
"Even on the day he went missing, he had left his phone at home," said Mr Mishra.
Mr Jha, a 1998-batch officer, was worked in the training section of the Ministry of Human Resource Development. He was not going to office and was on medical leave from September 28, the police had said.
